This one-of-a-kind parade started in 1941 after a group of Texas Cavaliers witnessed boats and barges decorated with flowers in the “floating gardens” of Mexico City. The Texas Cavaliers’ River Parade has been supporting local children’s charities since 1989. This colorful and vibrant parade not only lights up the streets during Fiesta, it also lights up a child’s face. 250,000 people attend the parade each year, but Texas Cavaliers only reserves 17,000 tickets for purchase.
